Abstract (en)
A process for forming a vapor-phase epitaxial growth layer on a silicon wafer having a buried layer of a high As or B concentration. This vapor-phase epitaxial growth process is performed in two steps of (i) performing a vapor-phase epitaxial growth at a relatively low temperature by using a reaction gas containing at least one kind selected from a group consisting of SiHxF4-x (x = 0 to 3) and Si2HxF6-x (x = 0-5) and at least one kind selected from a group consisting of SiH4 and Si2H6, and (ii) performing a vapor-phase epitaxial growth under a condition which allows a higher growth rate that in the step (i) by using a reaction gas containing SiH4 or Si2H6 which may or may not be accompanied with silane fluoride.
